The third upstream regulator identified in our analysis was FOXA2, that has demonstrated favorable prognosis based on TCGA data [32] and was predicted to regulate six genes that were downregulated in omental samples vs primary tumor (DLK1, GATA4, MAFA, MYOCD, NR1H4 and WNT5). However, FOXA2 was not differentially expressed in our data but rather another member of the FOX-family that encodes for transcription factor that is involved in all stages of ovarian development and function, FOXL2 [33]. Here, GATA4 is linked to neoplasm.
